41 The Art of Becoming Veitch CHAPTER 7 Truth and Reality in Whitehead’s Metaphysics Glen Veitch This paper seeks to challenge the idea of a determinate, singular reality within the philosophy of Alfred North Whitehead. In order to achieve this, it sets out to first establish a doctrine of panexperientialism as an integral and necessary part of Whitehead’s philosophy of organism. Second, it argues that there is an undervalued, inherent principle of perspective equally central to Whitehead’s metaphysics. Following from the combination of these two it will be argued that for the philosophy of organism specifically, and perhaps process ontologies broadly, the concept of ‘truth’ has significantly more resonance with coherence models than it does correspondence models. This line of reasoning is predicated largely on Whitehead’s reformed subjectivist principle, which by emphasising the experience of subjects as the ontological standard, defines reality in a way that removes singularity and determinateness for the sake of multiplicity and indeterminacy. In order to introduce the subjectivist principle, it is necessary first to elucidate the foundations for its inclusion within Whitehead’s metaphysics. There are three foundational principles upon which the subjectivist principle rests — the principle of process, the ontological principle and the principle of relativity. The Principle of Process The principle of process is summarised by the aphorism below, in which the entire philosophy of organism is presented. That how an entity becomes constitutes what that actual entity is; so that the two descriptions of an actual entity are not independent. Its ‘being’ is constituted by its ‘becoming.’ This is the ‘principle of process’. 199 This is simply an affirmation of the ontological primacy of event. The "two descriptions" mentioned here are a reference to the dual natures of an entity: the entity's formal nature as 199 Alfred North Whitehead, Process and Reality: an Essay in Cosmology, ed.
